## Summary This issue is to cleanup the `pages_multiple_versions_setting` feature flag, after the feature flag has been enabled by default for an appropriate amount of time in production. pages_multiple_versions_setting enables pages parallel deployments. The feature has been deemed stable and the feature flag should be removed. The feature has been productised. ## Owners - Team: ~"group::knowledge" - Most appropriate slack channel to reach out to: `#g_knowledge` - Best individual to reach out to: @janis - PM: @mmacfarlane ## Expectations ### What might happen if this goes wrong? The feature has been default-enabled for several months now, so there is no additional risk associated with the FF removal. ### Cleaning up the feature flag <!-- The checklist here is to help stakeholders keep track of the feature flag status --> - [x] Specify in the issue description if this feature will be removed completely or will be productized as part of the Feature Flag cleanup - [x] Create a merge request to remove `<feature-flag-name>` feature flag. Ask for review and merge it. - [x] Remove all references to the feature flag from the codebase. - [x] Remove the YAML definitions for the feature from the repository. - [x] Create [a changelog entry](https://docs.gitlab.com/ee/development/feature_flags/#changelog). - [x] Ensure that the cleanup MR has been deployed to both production and canary. If the merge request was deployed before [the code cutoff](https://about.gitlab.com/handbook/engineering/releases/#self-managed-releases-1), the feature can be officially announced in a release blog post. - [x] `/chatops run auto_deploy status <merge-commit-of-cleanup-mr>` - [ ] Close [the feature issue](ISSUE LINK) to indicate the feature will be released in the current milestone. - [x] If not already done, clean up the feature flag from all environments by running these chatops command in `#production` channel: `/chatops run feature delete <feature-flag-name> --dev --pre --staging --staging-ref --production` - [ ] Close this rollout issue. <!-- Uncomment the appropriate type label /label ~"type::feature" ~"feature::addition" /label ~"type::maintenance" /label ~"type::bug" -->
